Si3229x: ProSLIC Single-Chip Dual FXS Solution The Si3229x Dual ProSLIC devices, in a single package, implement two complete for- eign exchange station (FXS) telephony interfaces. The Si3229x devices operate from a KEY FEATURES 3.3 V supply and have standard PCM/SPI or 3-wire ISI digital interfaces. A pair of built-in dc-dc converter controllers can be used to automatically generate the optimal battery Two complete FXS channels in a single 8x8 mm package voltage required for each line-state, optimizing efficiency and minimizing heat genera- tion. The Si3229x devices are designed to operate with capacitive ultra-boost tracking Performs all BORSCHT functions battery supply for lower power, cost, and footprint vs. other tracking or shared battery Ultra-low power consumption supplies in the industry. Self-testing and metallic loop testing (MLT) is facilitated by the Patented low-power ringing built-in DSP, monitor ADC, and test load. The devices are available with wideband audio Patented Smart Ringing option for better than PSTN voice quality, DTMF detection, and Smart Ringing. Smart Ringing Reduces peak current with 2-channel reduces the peak current with 2-channel ringing for lower-cost ac-dc adapters. The ringing (Si32295/7) Si3229x devices are available in an 8 x 8 mm 68-pin QFN package.
